Basically, FL aims to facilitate the training model collaboration among participants without conveying their private data; thus, the private or confidential data is kept and never leaves their devices [1]}. The FL strives to optimize a global loss function \(F(w)\)  through an FL optimization objective that can be calculated using the empirical risk minimization approach in Equation 1,
\(\min _w{F(w)}=\sum _{k=1}^{m}p_k F_k(w)\)
